Exams from previous instantiations of similar courses.

Here are sets of PDF files of exams, most without answers, from my Biochemistry
461, 463, 465, and 674 courses. 465 and 674 are grouped because they cover
roughly similar materials. Use at your own risk. The fields and my understanding of
them have evolved. Please let me know if you find egregious errors (no regrades!)
or especially useful problems.

If you are using these to study, I recommend downloading the blank exams, doing your best to complete them on your own, and only then looking at the keys.
